Gravity Concentration in Artisanal Gold Mining

The principle of gold concentration in centrifugal equipment is the separation of gold from gangue mineral particles based on the difference in the settling velocity (Chen et al., 2020) . When the particles are subjected to the normal gravitational force (G-force = 1), like in a jig, a gold particle with a diameter of 0.02 mm falling in water reaches the same terminal velocity as a quartz particle of 0.07 mm.
